LE/shmania major. Infection of human monocytes selectively induces production of chemokines
No full textLeishmania are obligate intracellular parasites of monocytes, that may cause systemic disease or skin manifestations in humans. Leishmanial lesions are constituted of infected cells surrounded by macrophages interspersed with lymphocytes and polymorphonuclear cells (PMN). Since leukocyte infiltration is a common event of any inflammatory response, and monocytes are a major source of cytokines with chemotactic properties for PMN (IL-8) and for monocytes (MCAF), we asked whether L major might induce monocytes production of chemokines. Human monocytes were infected with L major ; supematants, that were collected after 18 hours of incubation, had chemotactic properties for monocytes as well as for PMN. Anti-MCAF Ig neutralized up to 52% of the monocyte chemotactic activity while anti-IL-8 neutralized up to 73% of the PMN chemotactic activity. Then we investigated whether chemokines expression by Le/shmama-infected-monocytes were accompanied with production of proinflammatory cytokines. TNF-o and IL-1II were detected at concentrations about 20 times lower than IL-8 in supematants derived from J.e/sftmama-infected monocytes while LPS was effective to the same extent to induce TNF-a, IL-1S and IL-8 secretion. These results suggest that L. major might induce a selective activation of monocytes for chemokines production to determine the recruitment of host cells permissive to the parasite
Cotton & Thrift: Feed Sacks and the Fabric of American Households.
No full textPrinted cotton sacks are currently fashionable aspects for material culture research, particularly in the costume and quilt history communities. Beginning in the late nineteenth century through the 1960s, these mass-produced sacks were relied upon by rural America as a valuable source of free fabric for clothing, quilts, and home décor. White cotton sacks were ubiquitous beginning in the last half of the nineteenth century; sacks printed with designs would come onto the market in 1937. Large households and farms required significant quantities of flour, sugar, and other staples, as well as animal feed, particularly chicken feed, all of which began to be packaged in cotton sacks at the beginning of the twentieth century. Companies such as the Imperial Sugar Company of Sugarland, Texas, and the Robert Nicholson Seed Company of Dallas, Texas, switched from jute and burlap bags to cotton in order to help ease the cotton slump that hit farmers throughout the South in the early 1920s. As the use of cotton sacks increased, whether the sacks were used to package human consumables or animal feed, these fabrics became colloquially known as “feed sacks.”
In 2015, more than 5600 printed cotton sack pieces came into the holdings of the Museum of Texas Tech University in the Pat L. Nickols Cotton Sack Research Collection. The Nickols Collection includes white sacks, printed partial and whole cotton sacks, swatches of printed sacks, instructional booklets, garments, quilts, quilt tops, and decorated white sacks. Combined with earlier and subsequent individual donations, the almost 6000 feed sack pieces held by the Museum of TTU make this the largest collection of feed sack materials to be assembled by an American museum, and likely the largest such collection in public hands. The Nickols Collection was brought to the museum in support of research, thus this publication serves to both showcase the breadth of the Pat L. Nickols Printed Cotton Sack Research Collection and also serve as a comprehensive visual archive for these important artifacts of rural American material culture
Re-presenting culture and the self: (Dis)agreeing in theory and in practice
No full textWe try to show that the fundamental grounds of psychological thinking about the domains of ‘culture’ and ‘the self’ (and their possible connections) are necessarily representationalist in the Cartesian sense. Rehearsing Heidegger’s critique of representationalism as the basic wrong turning taken by modern thinking generally (and by psychology in particular) with respect to what human being is, we move on to the possibility of a counter-representationalist re-specification of the concept of culture. Here we mobilize ideas from Husserl and Heidegger (again), and also from the basic ethnomethodological theory of Sacks and Garfinkel, to argue for the primacy of culture as an order of practical-actional affairs that makes conceptualizations of a putative ‘self’ always an effect of, and subsequent to, that very (cultural) order. Accordingly, we end by briefly analysing an actual case of an explicitly cultural use of a supposedly intensional term, ‘agree’

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Square Dancing with the Stars to Enhance Dynamic Hirschman Linkages?
No full textIn this Presidential Address, the author takes the reader on a reconnaissance of his life and time as a regional scientist. He points out scenery he found scintillating along the way, hoping that some may pick up the banner and chew on a few of the ideas for a while. He suggests a revisit to Albert O. Hirschman’s notion of key sectors and more empirical analysis related to Marcus Berliant’s and Masahisa Fujita’s notion of knowledge creation and transfer.Presidential Address, San Antonio, Texas, March 29, 2014 (53rd Meetings of the Southern Regional Science Association
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
